Start webpagetest with bookmarklet

Hi

I’m trying to start webpagetest with bookmarklet. My bookmarklet code is:

javascript:void(window.open(%27https://www.webpagetest.org/?url=%27+window.location.href,%27_blank%27));

Bookmarklet opens webpagetest.org, fills the current page’s url into the url field (till now everything ok) - but doesn’t start the test.

How can i improve the bookmarklet to start the test?
